The bidding process (or lack thereof) for the PBA television rights was very advantageous to ABS-CBN. The giant network asked for a one month window of exclusive presentations and negotiations before any other network was allowed to even tender a proposal. The PBA and ABS-CBN met at least 5 times negotiating back and forth so most of the original terms proposed by ABS already had comments and changes that made the proposal better for the league.
Normally, terms of reference are sent out to all who are interested to bid for the rights. Then based on those terms, each network tenders a bid on their capabilities. So for a network to get an exclusive window is a tremendous advantage because they are able to get feedback and improve their proposal along the way. It seems that ABS-CBN's first bid was unsatisfactory or even the 2nd presentation since they had to go to a 3rd, 4th and 5th meeting. Only when ABS was able to fine tune their proposal did the PBA invite the other networks to come in.
Solar was given 2 days to prepare a presentation. ABS was given about 2 months. ABC5 was accorded the same 2 day timeframe which they declined citing lack of time and change in programming direction. We'll see how the PBA decides on this.
